The fulcrum-pin d2 is disposed so that the distributor-head Z may swing into o erative position in the center of the cupola Fig. l) and into a vertical or inoperative position (Fig. 2), so that by swinging said beam, the distributor may be rendered operative during the charging and readily withdrawn from the cupola toward the end of the heat and after the last charge has been depliveied to and VIhe earn Z5 is -sh'a'ped' Vin Ycross-sectionWand its fulcrumpin Z2 is supported by the bracket-plates f 3 which are fixed to vertical angle-iron bars CZ which are fixed to the cupola wall and the door-frame a. Beam CZ is confined transversely between the plates CZE so it will swing vertically only. The beam moves through a slot b3 formed in the charging floor B adjacent the cupola when the distributor beam is in its inoperative position. Adjacent said slot, the charging floor is supported by a frame-work consisting of an I-shaped beam Zi* which extends under the floor and is fixed to the girders b5 on which the floor B is superposed, I-beam sections ZJG at the sides of slot b3, each having one end fixed to beam b4 and its other end to one of a pair of channel beams ZJ? which are fixed to the girders b5.

The counter-weight Z3 preferably consists of a series of plates or sections which are removably secured to the beam by bolts Zal so that the effective weight may be varied to afford the desired assistance to the operator in shifting the beam, which is usually done by inserting a hook on a suitable rod through the charging opening and lifting the inner end of the beam eZ. When the beam is in its inoperative position, shown in Fig. 2, the counterweight will hold it against displacement.

In some instances, it is also desirable to adjust the position of the distributor head rela.- tively to the fulcrum Z2 of the beam OZ by adjusting the beam. For this purpose, the web of the beam YVcZ is provided with an elongated slot CZ through which the pin Z2 passes and with series of holes (Z9. Bolts d10 are adapted to pass through said holes and to clamp reinforcing plates (Zn to said web. By removing the bolts d10, the beam may be adjusted longitudinally to bring the distributor into the desired position in the cupola. rlhe head Z is composed of an upper convex section Z13 which fits over and projects laterally from the flanges of beam cZ and a pair of lower sections CZ which lit against and are secured to the web of the beam by bolts 15. Bolts LZ1", with countersunk heads, secure the upper and lower sections together. An arched plate d" is secured to the top of the beam adjacent the head to deflect the material from, and to protect the beam. A lug d is secured to the beam cZ to stop the car at a uniform angle or position in dumping.

In the discharging of iron from dump cars,

the distributor defiects the metal so it will be impacted against the cupola wall of refractory material. To prevent disintegration of the wall, the cupola is lined with an annulus II of metal which consists preferably of a series of arcuate hollow blocks h set into the refractory material of the wall of the cupola. This annulus is extended vertically throughout the area adjacent the distributor where the mateia isiinpacted against the wall.

The opei follows: Normally, when the cupola is in operation and has been charged, the door a2 will be closed and the beam d will be in its vertical position illustrated in Fig. 2. Zhen charges of iron or coke are to be delivered into the cupola, the door is lifted and the beam CZ is swung into its horizontal position to bring the distributor-head into its operative position in the cupola. The car of material will then be run against the abutments Zi and tilted until it strikes stop Zlg so it will dump the material therein at a definite or predetermined direction, as illustrated in Fig. l. The material discharged will be directed onto the top of the distributor Z and the deflector plate ZU and thereby deflected into substantially all direction so that the material, when it falls on the bed in the cupola, will be substantially uniformly distributed throughout. After the cupola has been charged and more particularly toward the end of a heat, the beam d will be swung into its vertical and in operative position, as shown in Fig. 2, so the l o ation ofV the apparatus will be asV distributor will not be melted. During the charging of iron, the metal lining H will relieve most of the impact and thus protect the refractory wall of the cupola.

The invention exemplifies charging apparatus for cupolas which is adapted to be readily moved into and out of the cupola for speedy operation in connection with charging; in which a tilting beam is utilized to swing the distributor-head into and out of theV cupola; which be readily adapted te cupolas of usual construction; which comprises a readily operable dump-car for discharging loads into the cupola from a charging floor; and in which provision is made for preventing the disintegration of the re fractory material by impact from the material dumped into the cupola.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims, without departing from the spirit and scope of the invention.
